Simple mixin class in Python extracted from my framework Pyttman, mitigating the need to override __repr__ in convoluted ways over and over.
class PrettyReprMixin:
"""
Mixin providing a common interface for
__repr__ methods which represents classes
in a very readable way.
- How to use:
Define which fields to include when printing the
class or calling repr(some_object), by adding their
names to the '__repr_fields__' tuple.

Timer/Counter and Interrupt cheat-sheets for the Atmel ATMega324A microcontroller

AVR Interrupts

Each of the pins on the AVR may have multiple functions. For example, pin D0 and D1 are able to serve as receive and transmit pins for serial port one, respectively. Similarly, a number of pins on the AVR are able to transmit interrupt requests to the CPU when they receive a particular signal. How to implement this functionality is shown below.

Register Summary

Register Name Purpose of Register
PCICR Pin Change Interrupt Control Register (Enable interrupts for a particular set of PCINT ports)
PCIFR Pin Change Interrupt Flag Register (When a logic change triggers an interrupt on a particular PCINT pin, the corresponding flag will be set)
PCMSK0 Pin Change Mask Register (Select whether interrupts are enabled on a particular PCINT pin)

Call functions through the PollCache object for only receiving output from the function if new output is detected.
class PollCache:
"""
This object is designed to act as a cushion between a
function or other callable, and its caller, and only
give returns when new data from the function is identified.
This way you can pass functions to an instance of this class
and loop indefinitely, where only new results will be returned.
The PollCache object will treat every function and its
